Which core HTML and CSS skills should you assess in candidates?

The core HTML and CSS skills you should assess in candidates include semantic HTML, modern layout systems, responsive techniques, accessibility, performance tuning, and CSS architecture with contemporary tooling.

• Semantic HTML for structure and meaning
• CSS Flexbox and Grid for robust layout
• Responsive patterns for devices and viewports
• Accessibility standards (WCAG, ARIA) for inclusive UI
• CSS architecture (BEM, ITCSS, tokens) for scale
• Performance, cross-browser testing, and tooling

1. Semantic HTML and document structure

• Element choice maps content purpose to markup, improving structure and machine readability.
• Landmarks, headings, and lists align with assistive technologies and indexing.
• Tags drive browser defaults and accessibility trees, shaping navigation and focus order.
• Consistent patterns reduce overrides, simplify styling, and improve maintainability.
• Linters and validators enforce rules that prevent regressions and hidden defects.
• Code reviews catch misuse, ensuring templates remain adaptable and future-proof.

2. Modern CSS layout: Flexbox and Grid

• Flexbox handles one‑dimensional alignment, while Grid manages two‑dimensional placement.
• These systems replace float hacks, enabling predictable, maintainable layouts.
• Properties like gap, auto-fit, and minmax deliver adaptive, fluid arrangements.
• Fallbacks and feature queries keep experiences stable across older browsers.
• DevTools visualization accelerates debugging of track sizing and alignment.
• Layout tokens centralize spacing and breakpoints for consistent composition.

3. Accessibility (WCAG, ARIA)

• Standards ensure perceivable, operable, understandable, and robust interfaces.
• Inclusive components reduce barriers for keyboard and assistive tech users.
• Semantic roles, labels, and states expose intent to screen readers accurately.
• Focus management and skip links enable efficient navigation across views.
• Color contrast and motion preferences respect user settings and comfort.
• Automated checks plus manual audits prevent violations before release.
